Just set up 802.1x authentication on a Cisco Wireless LAN controller WLAN for the first time. My objective is to get Active Directory authentication working for my WLAN, accessible by both corporate laptops as well as blackberry and iphones.
I set up my WLAN with 802.1x auth pointing to a radius server. The Radius server in question is a Windows server 2008 R2 virtual machine with the Network Policy Server role. I installed IIS and submitted a cert request with the internal FQDN of the server. I got my trusted cert back and imported it into the Radius server. I then configured my network and connection policy with PEAP authentication (specifying that certificate and everything worked perfectly.
